CIVIL JET

Excellent Post Ann.  I think this is a great step in the right direction.   Every engineer realizes we are years away, if ever, from eliminating our complete dependence upon fossil fuels BUT, advances such as this can insure we maintain usable quantities for future generations.  Finding a suitable substitute for food grade biomass is truly a significant breakthrough.  As with every thing else, I suspect the cost will lessen as time goes by the technology to improve yields will increase.  Again--great article.

Thanks for clarifying, jhankwitz. What will get costs down is higher volumes, which means we have to start somewhere. I think this is one of those areas where government can help, and apparently the Canadians (and Europeans) agree.

I'm all for clean air, that's why I drive a Prius.  The point is that the airlines cannot afford to pay more for fuel.  They already have the least polution per man mile than any form of transportation.

jhankwitz, I don't know where you live, but I'm in California, with the highest gasoline costs in the nation. While I'd rather not pay more for anything--who would?--I pay more for gasoline without complaint knowing that we are meeting higher standards for clean air.

You're welcome, Elizabeth. Too bad the US isn't following more closely in the footsteps of the Canadians who accomplished this milestone.

This is great news! Advancements in bio fuel are the way forward for reducing dependence on oil and running cleaner vehicles across the board. Bravo to the airline industry for doing this type of research. I personally hope it leads to more success in the future and eventually the predominant use of this kind of biofuel. Thanks for covering.

I agree, Ann. The whole business of creating biofuels will likely go through many permutations before the industry settles on a few paths that are efficient and meet evolving regulations. This test, however, is just one more indication that there will be a significant biofuel industry.

Zippy, the smell of french fries may be prevalent in recycled cooking oil from restaurants used in cars with converted engines, but it's got nothing to do with commercial biofuels. Biofuels are derived from specifically grown crops, food-based or otherwise, produced with a variety of processes. To date, the main reasons biofuels have been blended with petro-based fuels have been a) performance and b) cost.

Ann, outside of the potential cost and availability issues, are there any technical reasons that a biofuel cannot be substituted 100% for aviation purposes?  Other than the pervasive smell of french fries at the airports, of course...   :)

Thanks, Rob. I think regardless of any other factors or considerations, the fact that this jet flew successfully on 100% biofuel is a very encouraging development. The jump from 30 to 50% in blends to 100% is insanely high, and a major first.
